The main goal of this paper is to answer the question whether a fuzzy PI control can provide better performance than a conventional PI/PID control in the case of a wind energy conversion system with a Doubly-Fed Induction Generator (DFIG) connected to a power system. The paper emphasizes the main advantage of fuzzy PI controllers: their ability to produce a non-zero control increment even when the output error is zero, but its derivative is not, proving a better performance than a conventional PI/PID solution for the control of high-order and strongly oscillating processes (with an error repeatedly crossing zero). This remark, according to the authors’ knowledge, has not been encountered in the specialized literature, being valid also for the fuzzy control of other strongly oscillating processes. To prove the above, the research presents a comparative study on the excitation control of a DFIG, using fuzzy PI controllers, respectively conventional PI/PID controllers. The goal of the control system is to keep constant the generator terminal voltage under some external disturbances action such as variations of the mechanical torque (due to wind speed changes on the wind turbine) and electrical load/unload (by connecting/disconnecting local consumers). Based on comparative analysis of type-1 and type-2 fuzzy PI control systems, it was concluded that, for the considered process (DFIG), type-2 fuzzy controller does not significantly improve the control performance. Therefore, the type-2 fuzzy controller is not justified, being even more complex and difficult to tune. The comparative study carried out between the fuzzy PI control solution (type-1) and the classical solutions using PI/PID controllers shows that the fuzzy strategy provides superior performance (smaller settling-time, shorter duration oscillations), both in case of a slow mechanical disturbance (mechanical torque variation), as well as for fast electrical disturbances (load/unload). It should also be highlighted that the DFIG is modelled as a nonlinear system of the 7th order (using Park’s classical d-q equations) ensuring an increased accuracy for the obtained results in the context of fast transient regimes specific to the considered electrical process
